You fulfil the bet

You approach Ellen as she catches her breath after the massive orgasm that Amy just brought her to. You lie down next to her and cup her face gently in your hand, then kiss her softly.

"Are you okay, Ellen?" you ask. She nods, glassy-eyed. "We don't have to if you don't--"

"A bet's a bet," she says, cutting you off. She leans in close and whispers in your ear, "I lost on purpose. I want you to cum inside me."

You lift one of her legs and drape it over your hips, lining your cock up against her slit. You push your hips forward, entering her. She sighs into your ear as you fill her up from the side.

"Fuck yes..." she moans. "Your cock feels so good. Fuck me, Scott, fuck me please."

"Yeah Scott," Amy goads you on. "Pump a hot load into her."

Ellen looks deep into your eyes, "Pump a load of cum into me, Scott."

She's tired but eager, and you pick up your pace, driving your cock into her warm, wet pussy, making her gasp with each thrust. She presses herself tight against your body and buries her head against your chest as a new orgasm crashes over her. She quivers in your arms, pussy squeezing your cock inside, as she squeals softly into your chest. As her climax subsides, she pulls away from you, rolling to one side.

You follow, never withdrawing your cock from her clenching depths, and end up on top of her missionary. You hike her legs up and continue to fuck her at a rapid pace.

Amy takes a seat over her head and grips Ellen's hands, giving her something to clutch onto as she spirals into yet another massive orgasm. You start to feel your own climax beginning to rise...

"Cum, Scott," Amy says. "Fucking cum in her." Amy holds on to Ellen with one hand while she rubs herself with the other, her lust spurred on by the sight of you Ellen bucking against you in orgasm.

"I'm gonna cum, Ellen," you say. "Ready for me?"

Ellen can only moan in response. Amy's breathing also begins to deepen as she masturbates while watching you.

"Do it, Scott," Amy says, wild-eyed. "Ohh... fuck yeah, Give her that creampie. A bet's a bet! It's so... fucking... hot..."

You hold yourself deep inside Ellen's spasming pussy as you cum with her. Your cock unloads blast after blast of semen into Ellen's body as she shudders and moans though her latest orgasm. Amy smiles with glee as you inseminate her best friend.

You slump over Ellen's still form and the two of you lie there for a moment, just breathing together as your climaxes subside. The only motion now is Amy, furiously masturbating herself above you, **** for a climax of her own.

"Fuck... fuck... fuck!" she gasps, teetering on the brink, but not quite going over...
